RADIATOR AND COVER THEREFOR.

Application filed March 18, 1925.

This invention relates to an improved radiator for internal combustion engines as well as a front cover for the radiator.

The invention seeks, among other objects,

to provide a radiator which will function to efficiently cool the water flowing therethrough and which will be adapted for general use in lieu of engine radiators as now employed.

The invention seeks, as a further object, to provide a radiator employing air conducting tubes and wherein the water flowing through the radiator will be caused to circulate over and around said tubes.

A further object of the invention is to provide a front cover for the radiator which will be yieldably held to overlie the front face of the radiator, wherein said cover will be provided with openings to permit a flow 29 of air through the air tubes of the radiator, and wherein the cover may be adjusted to zlose said tubes. 5

And the invention seeks, as a still further object, to provide means accessible from the drivers seat of the vehicle for raising the front cover.

Other and incidental objects will appear hereinafter.

In the accompanying drawings:

Figure 1 is a front elevation of the radiator, a portion of the cover being broken away.

Figure 2 is a vertical sectional view through my improved radiator and cover.

Figure 3 is a detail sectional view on the line 33 of Figure 2, looking in the direction indicated by the arrows.

In carrying the invention into effect, I employ a radiator shell which, as shown in Figure 1, may be widened toward its lower end, and is formed with parallel front and back walls 11. Rising from the upper end of the Shell is a filler tube 12 normally closed by a screw cap 13. Extending transversely through the shell are vertical rows of parallel air tubes 14: which project throiigh the front and back walls 11 of the shell and are upset at their ends against said walls for rigidly securing the tubes in place.

As brought out in Figure 1, corresponding tubes of the several rows are alined horizontally while, as shown in Figure 2, the rows of tubes terminate short of the ends of the shell to define a receiving chamber 15 at the 55 upper end of the shell and a discharge chamher 16 at the lower end of the shell. Com

Serial No. 16,520.

niunicating with the chamber 15 is an inlet 17 and leading from the chamber 16 is an outlet 18. Thus, water entering the chamber 15 through the inlet 17 will flow clownwardly within the shell over and around the tubes 15 into the chamber 16 to thence discharge into the outlet pipe 18. Accordingly, the water will be efiiciently cooled by the currents of air flowing through the tubes.

lower edge is a medially disposed staple 23 with which is connected at one end a spring 24, the opposite end of which is engaged with the arm 22. Thus, the spring will yieldably hold the cover drawn down at the front of the radiator and will prevent flapping of the cover. Formed in the cover to register with the forward ends of the radiator tubes 14, are vertical rows of openings 25. At the upper end portion of the cover, these openings are elongated, as indicated at 25' while throughout the remaining major portion of the cover the openings are circular and are of a diameter corresponding to the diameter of said tubes.

Extending transversely through the radiator shell near the upper end thereof is a medially disposed casing tube 26 which extends through the front and back walls of the shell and is upset thereagaiust for rigidly connecting the tube with the shell. As shown in Figure the casing tube is preferably squared and journaled in the forward end of said tube is'a pulley 2T. Trained over said pulley is a cord or other flexible element 28 extending through the tube 26 and connected at its forward end to the staple 23 of the cover. The rear end of said cord is attached to a rack bar This rack bar mounted upon the instrument board 30 or other part of the vehicle convenient to the drivers and extending through the instrument board is a guide sleeve 31 freely accommodating the bar. Atits base end. the sleeve is provided with a plate 32 which screwed or otherwise seeureiil to the instrument board for connecting the sleeve therewith, and upstanding within the tube at its rear end a shoulder 38 to eoaet with the teeth of th bar.

As will now be een in view of the foregoing, the openings or the cover 1.) will norn'ially register with the radiator tubes lei so that air will be freely admitted through said tubes. However, should it be deemed likely in cold weather that the water in the radiator might freeze, the rack bar 29 is pulled rearwardly a short distanee l'or elevating the cover until the openings in the lower portion thereof are disposed out ol register with the corresponding tubes of the radiator, when the core-r will serve to cut of? eirru ation of air through said tubes. The openings at the upper end portion of the cover re elongated in order that when the cover is thus elevated. portions ot the elongated openings will still remain in istration with the tubes at the uppe' end portion of the radiator to permit a eireuh lion of air therethrougl: so that the heated water at the top of the radiator will he partially cooled. However, the slots 21 in the cover are of such length that the cover may be further adjusted upwardly for elosng all of the air tubes of the rat iator, when eireulation of air through the radiator will be completely out off. Freezing n ay thrs be eneetua ly avoidet. The rack bar prorides, 01 course, a means whereby the cover may be secured in adjusted position i 11 either raised lowered and l aeeordi irovide. an arranger; ent whereby the flow of air through the radiator tubes may be regulated to a nieety. To remove the cover, the heads of the stud are turned to aline with the slots 21 of the cover while the cord 28 is detached from the staple Q3 and the spring 24 disengaged from the arm -s, the cover may be displaced.

Having thus described the invention, what I claim is:

1. The combination with a radiator having a plurality of air tubes extending from front to rear thereof, of a rover overlying the radiator and provided with openings to register with said tubes, and means for shitting the cor-er to one position having the openings in the lower portion thereof disposed out of: register with the tubes at the lower portion of the radiator or to another position having all of the openings in the cover disposed out oi register with all oi said tubes, the openings near the upper end portion of the cover being elongated whereby when the cover is shifted to said first mentioned position said elongated openings will remain in registration with the tubes at the upper end portion of the radiator.

3 The combination with a radiator having a plurz lity of air tubes er-ztending iron] from to rear thereof, of a cover overlying the radiator and provided with openings to register with said tubes, and means for whittine; wrer to close sa d tubes, rert in ol said 01 eningrs being elongated whereby the cover may be shifted to a position closing certain of said tubes only.

3. The combination with a radiator having a plurality of air tubes extending from ont to rear thereof, of a cover overlying e radiator and provided with openings to register with said tubes, and means for shif ing the cover to close said tubes, certain of said openings being of a contour whereby the cover may be shifted to a position closing certain of said tubes only.

In testimony whereof I aii'ix my signature.
